They must be Indian citizens, male or female, aged between 16.5 to 19.5 years, and have completed 10+2 education. For the Air Force and Navy wings, Physics and Mathematics are mandatory subjects. Physical fitness and medical standards set by the defence forces must also be met. To prepare effectively, many aspirants choose the best NDA coaching in India, which provides expert faculty, structured study material, and regular mock tests. These coaching institutes enhance a candidate’s academic and physical readiness for the rigorous NDA selection process. Staying updated with official notifications is essential to ensure all eligibility requirements are met.
